The Symfony Finland site has an article posted introducing you to Symfony Encore, a tool that makes it simpler to manage frontend libraries and dependencies via Webpack.

Symfony Encore is a wrapper for the JavaScript module bundler Webpack. Webpack is used to manage Front End assets like JavaScript, CSS and image for browser consumption, often with conversion step from a source format like SASS. Encore provides an opinionated way to add Webpack to your Symfony projects.

[...] Earlier this year I experimented with sharing a state object with Symfony and different front end tools. Recently I ported the Symfony 3 application to Symfony Flex. Now I will continue the evolution of the app by adopting Symfony Encore to the project.

The article briefly introduces Encore and what functionality it provides before getting to the installation (via yarn) and configuration that it installs by default. The post then goes through the setup of SASS, using assets in your pages and running builds.

On the Symfony blog they've released an announcement about the release of a tool that wants to help make it easier for Symfony developers to work with frontend resources using the Webpack standard: Webpack Encore.

For everyone that has hit [the barrier of complexity in frontend dependencies and compilation], I'm very excited to show you something we've been working on for the last few months: Webpack Encore.

Encore gives you powerful CSS and JavaScript processing, combination, minification and a lot more, wrapped up in a simple API that's built on an industry-standard tool (Webpack).

He includes an example of the Javascript configuration to build out the Javascript, CSS and dependencies required for his build. He talks briefly about the conformity to the Webpack handling and how Encore fills that role in Symfony applications. The post ends linking to the project repository and the changes required to get the package installed.
